A base for roller skates includes a skeleton and a reinforcing shell. The skeleton is made of a first material through one-time processing and is formed with a plurality of hollow areas. The reinforcing shell includes a plurality of inlaid structures respectively embedded in the hollow areas is directly disposed on the skeleton by injection molding with a second material. The second material is different from the first material. Two roller frame mounting hole sets on the base for roller skates are directly formed by the skeleton, and a brake block mounting hole and a treading platform on the base for roller skates are formed by the reinforcing shell. The base for roller skates is not made of single metal material like prior arts, making it capable of reducing fracture due to the hard and brittle characteristics of the material used in prior art.

In a specific embodiment, the at least one neutralizing agent comprises i) mono and/or divalent metal compounds and ii) ammonia compounds and/or amine compounds.

A metal resin composite-molded article which can suppress deformation induced by laser processing in a technique for improving the adhesion between a metal plate and a resin by forming grooves on the surface of the metal plate by means of a laser, even if the metal plate is thin. A metal resin composite-molded article obtained by insert-molding a resin composition on a metal plate having a thickness of 500 μm or less, grooves are formed on the surface of the metal plate in which the resin composition is inserted, the width of the grooves is 30-300 μm, the depth of the grooves is at most 24% of the thickness of the metal plate, and the ratio of the width to the depth is 0.1-2.5.

The invention provides a base for roller skates comprises a skeleton and a reinforcing shell. The skeleton is made of a first material through one-time processing and is formed with a plurality of hollow areas. The reinforcing shell including a plurality of inlaid structures respectively embedded in the hollow areas is directly disposed on the skeleton by injection molding with a second material. The second material is different from the first material. Two roller sets of frame mounting hole on the base for roller skates are directly formed by the skeleton, and a brake block mounting hole and a treading platform on the base for roller skates are formed by the reinforcing shell. The base for roller skates is not made of single metal material like prior arts, making it capable of reducing fracture due to the hard and brittle characteristics of the material used on prior arts.

An encapsulation assembly includes a body located at edges of the functional glass; and a conductive module embedded in the body or located on a surface of the body, and electrically connected to a functional module on the functional glass. The process of forming an encapsulated glass from the encapsulation assembly for a functional glass can omit complicated manufacturing steps and save materials and thus reduce costs. An easy and stable control of the functional module in the glass can also be accomplished. Moreover, it is much easier to form an encapsulated glass from the glass, which facilitates glass mounting.

A method for manufacturing a composite structure having first and second structural members includes the steps of: (A) placing a plate in a forming mold having a first molding member, and a second molding member with an injection hole; (B) moving the first molding member toward the second molding member to stamp and deform the plate; (C) injecting a molten substrate onto the plate via the injection hole to stamp and deform again the plate so as to form the first structural member; (D) removing an assembly of the first structural member and a solidified substrate from the first molding member; and (E) removing an excess part of the solidified substrate to form the second structural member.

The present application relates to a polymer composition comprising from 20 wt % to 30 wt % of a polycarbonate; from 40 wt % to 60 wt % of a polybutylene terephthalate; from 5 wt % to 30 wt % of a reinforcement fiber; from 1 wt % to 10 wt % of glass bubbles, and from 0.3 wt % to 2 wt % of transesterification inhibitor, all contents are based on the total weight of the composition. The polymer composition according to the present invention has improved adhesion to the metal (especially aluminum), even after annealing and anodizing processes are applied.

A method for joining dissimilar materials includes forming a first recess and a second recess by irradiating a surface of a first member with laser light, the first recess and the second recess being cut into the surface obliquely at angles different from each other, and joining the second member to the surface of the first member with a part of the second member engaging with each of the first recess and the second recess by melting the part of the second member lower in melting point than the first member to cause the part of the second member to flow into each of the first recess and the second recess and solidifying the part of the second member.

A method for producing a media-tight material composite, in particular comprising a metal solid body and an optionally electrically insulating plastic at least partially surrounding the solid body, preferably as a component of a preferably shielded electrical interface, wherein surfaces of the solid body that the plastic contacts are subjected to a surface pretreatment in order to promote the adhesion of the plastic to the solid body. The disclosure further relates to a cylindrical metal sleeve, in particular as part of a plug connector, and a plug connector or sensory comprising a metal sleeve, produced by the foregoing method.
